This invention relates to new and luseful improvements in a tooth powder dispenser.

More specifically, the invention proposes a powder dispenser which is characterized by a casing having a top neck for receiving and supporting a receptacle of powder, and Aalso having a horizontal cylindrical portion with a bottom discharge chute, and certain vmechanism within said cylindrical portion for controlling the discharge of a predetermined quantity of powder.

More specifically, the invention proposes to arrange a measuring pocket member lwithin the cylindrical portion operable in a certain way.

Still further the invention proposes an arrangement by which the pockets of the Vmeasuring pocket member may be varied to cont-rol lthe amount of discharged powder.

For further comprehension of the invention,

and of the objects and advantages thereof, `reference will be had to the following description and accompanying drawing, and to the appended claims in ywhich the various novel features of l the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 4 is a fragmentary enlarged elevational view similar to a portion of Fig. 1 but disclosing a tooth -powder dispenser Iconstructed in accordance with a modified form of this invention.

Fig. 5 is a transverse vertical sectional view taken on the line 5 5 of Fig. 4.

Fig. 6 is a fragmentary lperspective view of a portion of the measuring pocket member used in Fig. 4.

'The tooth powder dispenser, in accordano with this invention, includes a casing I0 having a top neck II for receiving and supporting .a receptacle of powder I2, such as tooth powder or other powder. The casing I0 is also provided with a horizontal cylindrical `portion i3 having a bottom discharge chute I4. The casing I0 is on a bracket I5 by which it is supported. The bracket I5 has a base section I6 secured to a wall Il or other support by fastening elements I8. The bracket I5 is also provided with a stem section I9 connected with the back of the casing I0,

A measuring Vpocket member is turnably axially mounted through the cylindrical portion I3 of ,the casing I0 and is connected with a prothese parts.

jecting lportion in the form of an external knob 2| by which it may -be turned. The measuring pocket member 20 vessentially comprises a rod 22 mounted axially in the cylindrical portion I3. The .rod I'22 is mounted on the end walls of said cylindrical portion I3. AOne end vof the rod 22 projects, and thisprojecting end is provided with the said knob 2I by which it 'may be turned. In addition to the rod 22 the measuring pocket includes a plurality bf radial vanes 23 mounted on and proiec'ting from the rod 22. These vanes divide off a plurality of measuring lpockets 24. As illustrated in Fig. '3 there are four vanes 23 dividinglof four of the pockets '24.

Means is provided for assisting in selectively aligning the pockets 24 of the measuring pocket member 20 with the said discharge chute I4. This means comprises a ratchet 2'5 mounted on the rod 22 and having a notch 275 for each vane 23. A pawl `2l is mounted on `the wall of the cylindrical portion I3 and engages the ratchet 25 so as `to assist in selectively turning the pocket member. yAs illustrated in Fig. 3 the rod 22 :should be turned counter-clockwise until one feels and hears the pawl 21 'snap into the next notch 26. Tn the `new position, a new one of the pocket-s .24 will have been aligned with the .discharge chute I4. Y

.il-n ,Figs/4 4to 7 inclusive a modiiied form of the invention has 'been ydisclosed vwhich is similar 'to the prior form but distinguishes in the fact lthat a pair of shutters 28 are slidably mounted on'the pocket member 20" and are associated Ywith means by Vwhich the shutters 28 may be Ymovedfto kreduce `the vcapacity of Ythe pockets. More specifically, the measuring pocket member 20" .comprises a tube 22 coaxially turnably mounted through the cylindrical portion I3 and having one end projecting from one end wall of said portion. 'This projecting .end is provided with 'the knob 2l 'by which 'the tube 22 may be readily turned. A plurality of varies 23 is mounted `'radially :on 'the tube 22 and form the various pockets of lthe .pocket member.

The Vshutters 28 are lin the nature of relatively wide :discs having a plurality of slots 3U and a central .opening 3| for Vreceiving the vanes 2,3 and the tube 22'. More specifically, the shutters 28 'are mounted on the end portions of the :measuring pocket member 20. Small crescent shaped -ller members 32 (see Figs. 4 and 5) are mounted within the casing I 0 and extend over the top portions of the shutters 28 to prevent powder from entering the compass occupied by Each shutter 28 has an internal ypin 33 which extends through elongated slots 34 formed `in the tube 22 and engage between threads 35a and 35b formed on the rod 36 ro- :ta-tively mounted through the tube 22.

rlhe rod 36 has a projecting end provided tween the vanes 23.

'smaller quantity of powder.

Thus the shutters 28 may be moved together and so reduce the compass of the pockets be- In othevrrespects this form of the invention operates as in the previous form.

They will then receive a.

Cil

said chute in certain turned positions of said tube, spaced shutters slidably mounted on said tube, pins formed on said shutters and extended into said tube through spaced elongated slots formed in said tube, and a rod projected through said tube and formed with spaced threaded sections engaged by said pins for moving said shutters when said rod is turned relative to said tube for controlling the capacity of said pockets, one

of said threaded sections being left handed and The knob 2| must be turned to rotate the measuring pocket member "together with the` shutters 28 and so successively placeidifferent ones of the pockets in communication -with the discharge chute I4. Thus the powder is discharged. 'I'he tube 22' is-provided Withva ratchet immediately adjacent an end wall of the cylindrical portion I3. This ratchet 25 is engaged by a pawl 2l. The pawl and ratchet assists in selectively aligning the pockets of the measuring pocket member with the discharge chute I4 as previously described.
